NickCTaylor,
[QUOTE]Why do you dump fuel then?
The facetious answer is because they can! As per the certification regulations an aircraft has to be capable of landing within 15 minutes of a Max weight takeoff. An allowance for fuel dumping is permitted although you might be surprised at how many airliners do not have a fuel dumping system!
The ONLY requirement to dump fuel is due to the aircrafts performance limitations for the planned runway. Cardiff shouldn’t suffer from these!
